Re: Core Data Save As Binary Error
Have you changed the storetype to binary in info.plist file

I have a Core Data document based application.
Saving the file as XML or SQLite works fine.
Saving as binary results in an error: *** -[NSKeyedArchiver
encodeValueOfObjCType:at:]: this archiver cannot encode structs.
The struct in question is a transformable attribute using a custom
value transformer.
- (id)transformedValue:(id)value
{
return [NSArchiver archivedDataWithRootObject:value];
}
No where in my code do I call NSKeyedArchiver.
Why does the core data framework work fine saving as XML or SQLite
but not binary?

Re: Custom background in NSTableHeaderView
Hi,
CellAttributes are used by button and button cell for displaying
image and text accordingly, but tableHeaderCell doesn't uses these
attributes for displaying image and text.. Customize the
NSTableHeaderCell and draw the image and text in drawWithFrame method.
Thanks

Hi,
I am trying to display custom image and the attributed text into the

Background image
overlaps the text.
I am overriding NSTableView and doing two things.
1. setDrawsBackground:NO

Re: Multiple relationships between two entities
Create a Link Entity by adding another property linkType which decides
the normal or alternate link.
In Item entity make to-many- relationShip for relationship link

I'm just getting started with Core Data so go easy on me.
I am moving my existing app across to Core Data and I'm having
trouble with a few concepts.
At present (pre-Core Data) my app has a model object (Item) which
is used as the node object in an NSTreeController.
This model object has multiple ivars of another custom object
(Link) like so:
@interface Item : NSObject
{
Link* normalLink;
Link* alternateLink;
}
@end
I'm trying to replicate this in my Core Data model. I have set up
two entities, Item and Link. I have created two relationships in the
Item entity, normalLink and alternateLink, both pointing to the
Link entity.
Basically, I want each of these relationships to point to an
instance of the Link entity.
However, now I have a problem. My Link entity has one relationship
(item) which should be the inverse relationship, but that's not
possible because I can only have one inverse relationship.
I think I'm getting mixed up here, how should this actually be
modelled?

Wrong selection Index
I had a table with 3 columns(col1, col2, col3(buttonCell)) in which col1 and col2 columns are binded to an Array Controller .Col3 is button cell which is targeted to an action method. When changed selection by clicking the button , in the button cell target method if i ask for selection index on array controller i am getting previous selection index, and if changed my selection by clicking on a row which contains col1 or col2 i am getting correct selection index. Can any one suggest how to get the correct selection index in cell target method even my selection changes by clicking directly on button of a particular row.

problem with NSTimer
according to documentation for
beginSheet:modalForWindow:modalDelegate:didEndSelector:contextInfo: it
says that While the application is in the run loop, it does not
respond to any other events (including mouse, keyboard, or window-
close events) unless they are associated with the sheet. It also does
not perform any tasks (such as firing timers) that are not associated
with the modal run loop.
But in my app the timer i had created fires even my main window is in
running as Modal

self = [super init];

NSDistantObject exception when server trying to access registered clients using DO

I developed server and in that i vended an object to be accessible by
clients.In the client side i am getting the vended object, and getting

ask server for his queries and server replies to that. But on the
serverside if any updates goes, i had to inform client.so i thought of
registering the client and ping the client for the updates.In the

my server pings the client giving the following exception.

It looks like the above is separate from the below exception,
although probably related. That message is far from clear. An
Apple engineer may be able to help.
It seems to be saying that it has received an object identifier

@implementation ServerObject : NSObject
-(void)registerClient:(idNetClientProto)client {
You didn't show the NetClientProto protocol, although I'm guessing
it's pretty simple.
You didn't comment here. I guess I was too subtle. I was asking to
see the protocol declaration.
[serverObject performSelector:@selector(registerClient:)
withObject:self];
Why are you using -performSelector:... here? What's the
declaration of 'serverObject'?
Best practice is to have a protocol for each side of the
connection, defined in a header that is shared between the code
bases. Then you don't have to relying on things like -
performSelector:... You could just invoke -registerClient:
directly.
Such a protocol is also where you'd specify bycopy, oneway, and
similar specifiers.
Furthermore, you should use -[NSDistantObject
setProtocolForProxy:] for efficiency, and probably
NSProtocolChecker (on the server side) for security.
Thanks , and i will probably implement this

Registering Clients using DO
I am developing a client/server application using DO. In server an
object is vended to be accessible by clients.In the client side i am
accessing vended object and get required info from server.Every thing
works fine. Until now my client queries server and server replies to
that. But on serverside if any updates goes, i had to inform client.so
i thought of registering the client and ping the client for updates.So
in Client side i get vended object and registered it to server.When my
server pings the client its giving error *** NSDistantObject
initWithCoder: 0x1 not given away for conn 0xf8937f0
I think my registering of client with server goes wrong , can anyone
suggest me what i am missing here.If any sample code that would be
great.

Hmm. I was wrong to suggest sampling. I doesn't resolve to
specific lines of code, just functions/methods. Better to break
into the program using the debugger (Control-c if using gdb
directly, the Pause button in Xcode's debugger) to get the specific
line within the -serverObject method.
Of course, line numbers won't be meaningful to me without your whole
source file, so just show the contents of the line.

Long Time Dealy When getting Vended Object
Hi,
Really going mad, it is taking long time response when i am trying
to get vended Object from the remote machine which doesn't exist in
the network. .
I am facing same long time delay(more than 60 sec) when i am trying
to get vended object from the remote machine which gone to sleep.
Below is the code
-(id)serverObject {
id serverObject = nil;
@try{
serverObject = [[self serverConnection] rootProxy];
}...@catch(NSException *exception) {
serverObject = nil;
[self destroyConnection];
}
return serverObject;
}
-(NSConnection *)serverConnection {
if(!serverConnection) {
NSString *webAppURLString = [[NSUserDefaults standardUserDefaults]
objectForKey:kPXWebAppURL];
NSString *host = nil;
if(!(webAppURLString [webAppURLString length] 0)) {
host =[[NSProcessInfo processInfo] hostName];
} else {
host = [[NSURL URLWithString:webAppURLString] host];
}
NSSocketPort *port = [[NSSocketPort alloc]
initRemoteWithTCPPort:PORT_NUMBER host:host];
serverConnection = [[NSConnection alloc] initWithReceivePort:nil
sendPort:port];
[serverConnection setDelegate:self];
[serverConnection setRequestTimeout:1.0f];
[serverConnection setReplyTimeout:1.0f];
[[NSNotificationCenter defaultCenter] addObserver:self
selector:@selector(handleConnectionDied:)
name:NSConnectionDidDieNotification object:serverConnection];
[port release];
}
return serverConnection;
}
Please help me out in this

Re: Long Time Dealy When getting Vended Object
Thanks, Ken for your Reply, Usually we will get time out exception when trying to get vended object that is not available but in the below case i use to get same exception after a long long delay and some times My app crashes Thanks SkiranKumar On 22-Apr-09, at 1:52 PM, Ken Thomases wrote: On Apr 22, 2009, at 1:14 AM, Kiran Kumar S wrote: Really going mad, it is taking long time response when i am trying to get vended Object from the remote machine which doesn't exist in the network. .

You can find out by sampling the process from Activity Monitor or breaking into the process with the debugger. The delay you're seeing is probably the TCP connection timeout. On most systems, it will take about 9 minutes for TCP to give up all attempts to connect and timeout. I would hope that NSConnection would implement its own timeout mechanism as an alternative to allowing TCP to exhaust itself. As near as I can tell from reviewing the documentation, the reply timeout should govern the -rootProxy method. Since you're setting that, then I'm not sure why it's not working. This might be a bug, which you should file at http://bugreport.apple.com .

SocketPort allocating
I had Distributed object which can used by any client, i am establishing connection using a port , every thing works fine.My object is vended and the client can use the vended object . But i am getting problem when i restart my server which supplies vended object. When i am restarting sometimes my socket is not get allocated , and this is beecause the socket is using by any of the client, how can i resolve this situation . NSSocketPort *serverPort = [[[NSSocketPort alloc] initWithTCPPort: 3002] autorelease]; aConnection = [[NSConnection alloc] initWithReceivePort:serverPort sendPort:nil]; NSRunLoop *runloop = [NSRunLoop currentRunLoop]; [aConnection setRootObject:[ServerObject sharedServerObject]]; Regards kiran ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

Popups Binding problem
Hi, I have two popups which I want to bind together; the first popup contains a list of Categories, which has an array of reports. The reports array is a content array of the second popup. I want to select a Category in the first popup and get a list of reports in the second popup. When user changes a Category, the popup updates with the corresponding list. When I open the APP, the popups are populated correctly, but the second one (with employees) doesn't update after Category change. Please Suggest me if any ideas Regards SKiran ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
